As soon as the leak case was concluded, Yu Cheng came to report it, and it seemed that Gu Zhengqi was very anxious about the air raid case.

"Please come in, Section Chief Yu!"

Soon Yu Cheng walked into the office with laughter all the way.

"Seated, this time I am fortunate to learn from you again, but I am really happy that I don't know what to do, and I will hurry up to report to you when I receive the order!"

Yu Cheng has always been tactful, talking about people when he sees people, and talking nonsense when he sees ghosts, not to mention the ruthless character of Ning Zhiheng, he is the one who deals with Ning Zhiheng the most in the intelligence department, and he is convinced of Ning Zhiheng from the bottom of his heart.

Ning Zhiheng also got up and came to Yu Cheng's side, and said with a smile: "Old Yu, I'm not your chief officer, don't be too polite, let's call me Zhiheng!" ”

Although Ning Zhiheng's position is higher than Yu Cheng, the two have no affiliation, Yu Cheng does not need to be honored as a seat, but Yu Cheng is old and sophisticated, how dare he call Zhiheng, he hurriedly waved his hand and said: "Seat, small places can't be arbitrary, don't scare me!" ”

After speaking, there was an exaggerated expression on his face, Ning Zhiheng was just polite, he didn't beat Cheng Ke less at the beginning, and gave him a few times, but now it seems that the effect is really good.

"Haha, then let it be! Come, let's sit down and talk. ”

Ning Zhiheng sat down on the side and said bluntly: "I heard that you were in charge of the air raid case from the beginning, how about it, after tossing for so long, have you found a suspicious target." ”

As soon as he mentioned the air raid case, Yu Cheng put the thick file in his hand on the table, his face suddenly became depressed, and he said with a wry smile: "There is no progress at all, sit down, let me introduce you to the specific situation." ”

After that, Yu Cheng carefully recounted the specific situation of the air raid that occurred a month ago, and then continued: "At that time, according to the situation at the scene, we judged that this was a purposeful attack by the Japanese, and the Japanese found out that Yi Dong was claustrophobic, and it was even possible to know that he had just accepted a new task to decipher the Japanese military code, so he couldn't wait to attack Yi Dong." ”

After listening to Yu Cheng's narrative, Ning Zhiheng thought for a while and said: "Your analysis is very correct, the reason why the Japanese used the method of air raids to kill Yi Dong is to make us think that it was just an accident, so as to cover up the fact that there is a traitor inside us and cover up for this traitor." ”

Yu Cheng hurriedly nodded and said: "That's exactly the truth, but if you want to cover it up, so the bureau ordered us to conduct an internal investigation, but the target has not been determined, and there are not many people who know that Yi Dong has claustrophobia, because every time the Japanese air raid, everyone hides in the nearby air-raid shelter, only Yi Dong is not there, and it is inevitable that they will inquire about each other, so his colleagues and neighbors may know about this matter, and the scope is not easy to determine."

However, knowing that Yi Dong took over the matter of deciphering the Japanese military code, only the core members of their decipherment team knew that the work of the decipherment team was very special and secretive, and they did not deal with other departments in normal times, and we had emphasized the secrecy regulations for the content of the code-breaking work, and we must not disclose it to the outside world, and there should be no possibility of information leakage, so we focused our target on the 18 members of the decipherment team. ”

"Eighteen members?"

"Yes, plus Yi Dong has nineteen, and there are a total of one hundred and three staff members in the decipherment room, but most of them are auxiliary service personnel, such as cleaning guards, but there are only nineteen core members, all of whom are the best decipherment experts and mathematicians in the country, and these people are the key targets.

The bureau ordered that the Japanese and the traitors think that we really believe that Yi Dong's death was an accident, and at the same time, we really can't torture these experts, this is all gold and silver babies, it really hurts people, this password work is all based on the brain, and if you don't work in the future, you can't do it. So I've been investigating the situation around them, but there are a lot of things under investigation, and I can't see a reason, so I'm just waiting for you to take over. ”

Ning Zhiheng opened the file, and there was a thick stack of investigation reports inside, and he couldn't help but sigh lightly, I have to stay up all night tonight.

"Old Yu, you see, I'm still dealing with the leak case, I have to go through the information you brought, and I can't find any clues for a while, so you go back first, I'll familiarize myself with the situation first, I'll call you tomorrow, let's go to the decipherment room to have a look, and then visit Yi Dong's family."

Yu Cheng also saw a pile of documents on Ning Zhiheng's desk, and quickly nodded in agreement, stood up and left.

Ning Zhiheng sent Yu Cheng away, looked back at the room full of documents and materials, couldn't help but let out a long breath, and began to deal with official business.

Ning Zhiheng didn't even go home that night, he looked through the information until late at night, and dealt with it directly on the sofa in the office all night, and early the next morning, after getting up, he simply freshened up, called Yu Cheng, and then left the second place and rushed to the headquarters.

At the door of the headquarters office, Yu Cheng had been waiting there for a long time, and when he saw Ning Zhiheng coming, he hurriedly greeted him.

"Sit, the location of the decipherment room is still some distance away, I'll show you the way."

Yu Cheng got into Ning Zhiheng's car, and the vehicle quickly drove some distance east, stopped at the gate of a compound, and then got out of the car.

Yu Cheng pointed to the door and said: "This is the decipherment room, deliberately separated from other departments of the headquarters, just for fear of attracting attention, the management is also very strict, the security is strict, all the staff here can not bring out a piece of paper, otherwise the military law will be engaged." ”

Ning Zhiheng looked at the gate, but there was not a single word bare.

Yu Cheng said with a smile: "The decipherment room department doesn't dare to sign a sign, I heard that there is a decipherment department in the United States called the 'black room', so everyone also calls this place the 'black room', in short, the level of secrecy is the highest." ”

Speaking of this, he sighed again: "Who knows that there is still an inner ghost!" ”

Ning Zhiheng asked his guards to stay at the door, he and Yu Cheng entered the gate, there was a team of guards guarding the door, and the officer on duty had already received a notice, and after checking the documents of the two people, he was released.

After Ning Zhiheng entered the compound, he looked around, there was no difference between this and ordinary big houses, it was estimated that it originally occupied the residence of large families, but the atmosphere inside was very depressing and quiet, there were also guards in the corridor and yard, and occasionally people walked by, and they were in a hurry, and they didn't pay attention to Ning Zhiheng and the two of them.

Yu Cheng was obviously accustomed to it, he took Ning Zhiheng into the inner courtyard, pointed to a few rooms and said: "These rooms are the deciphering team's studio, radio reception room, monitoring room, archive room, etc., the people inside are working, and now we can't enter." ”

Ning Zhiheng frowned and said, "Didn't you say that there is no progress in the decipherment work now?" So what are they doing? ”

Yu Cheng shook his head, shrugged his shoulders and said: "The ghost knows, these people are very arrogant, and if they ask them a little knowledge, they are impatient, and they never explain, and I have to accompany the smiling face." ”

At this time, a middle-aged man walked over quickly, stretched out his hands a few steps away, and said with a smile: "Director Ning, I heard that you came to inspect, so I immediately rushed over, what a slack!" ”

Ning Zhiheng smiled and stretched out his hand to shake it, and said with a smile: "Old Bian, Ning is uninvited, I'm going to disturb you!" ”

The person who came was Ning Zhiheng's acquaintance, Bian Deshou, the lieutenant colonel section chief of the telecommunications office, who was the head of the major team during the Nanjing period a few years ago, and had contact with Ning Zhiheng several times, and once assisted him in cracking the cheongsam case and the radio wave case, and the two of them can be regarded as old friends.

When Ning Zhiheng checked the information last night, he already knew that Bian Deshou was currently serving as the director of the decipherment room, and he did not know how to decipher the code, so he was only responsible for cooperating with the work of these experts in the decipherment room, similar to the position of the chief housekeeper.

Bian Deshou naturally didn't dare to be a little slacking off on Ning Zhiheng, the high-level military commander, he looked at Yu Cheng on the side, and knew why the two of them came, and hurriedly said with a smile: "Director Ning, if there is anything you command, I will definitely cooperate!" ”

Ning Zhiheng pointed to the studio and said, "Can I go in and have a look?" ”

Bian Deshou hurriedly nodded and said, "No problem, I'll arrange it immediately." ”

Yu Cheng on the side rolled his eyes, and said angrily: "Lao Bian, I've been here so many times, if you want to go in and take a look, you just stretch your face and say no, why are you so happy this time?" ”

But Bian Deshou didn't answer at all, pretended not to hear, turned around to arrange matters, and quickly walked back, asking Ning Zhiheng to come over, and Yu Cheng also hurriedly followed.

Bian Deshou looked at Yu Cheng, his mouth opened, and finally he didn't say anything, Yu Cheng also pretended not to see anything, and followed Ning Zhiheng into the studio.

The first workshop is a large radio receiving equipment, and there are eight operators with headphones to carefully receive and record various radio signals, and the sound of Didi is endless.

In the second room, there was a long square table with all kinds of data on it, and there were eight or nine telecommunications experts who were looking down and calculating, and no one looked up at the three of them.

Ning Zhiheng stepped forward and glanced at the materials on the table, an expert immediately reached out to block the materials, and put them away, looking at Ning Zhiheng with scrutinizing eyes, as if looking at a thief, if it weren't for Bian Deshou standing next to Ning Zhiheng, it is estimated that he would have called the guards.

Ning Zhiheng had no choice but to turn around and look at another man in his thirties on the side, who was filling in a set of numbers into a form, looked up at Ning Zhiheng, smiled slightly, and showed a friendly expression.

Ning Zhiheng also hurriedly smiled at each other, stretched out his hand to signal, and took a telegram from the table, all of which were arranged in ordinary Arabic numerals, Ning Zhiheng was just a little curious, but he didn't know anything about code breaking, so he looked at it twice and put it down casually.

Turning around and looking at the other experts, he silently corresponded them with the people in the materials he consulted, and then entered the third room, which were all desks, it seemed that the office space was relatively tight, everyone only had one desk, everyone shared a room, and there were several experts in this room who were calculating the data, and from time to time a new telegram was handed over by the operator.

The whole decipherment room was working very quietly, no one said a word, there was no communication between them, everyone was quietly busy.
